Patent CA-1135231-A (CA)
Inventor: JOHNSON LOUIS W
IPC: B02C2/00

Abstract: ABSTRACT     The crusher comprises a crusher head mounted about a gyratory shaft assembly.  The head comprises a mantle mounted on and secured to the shaft by a hold down cap assembly.  For this purpose, the shaft is formed with a screw threaded recess, and the cap assembly comprises a screw threaded bushing secured in the recess by external threads on the bushing, which is also provided with internal threads to receive a screw threaded shank of the hold down cap assembly.  The bushing is arranged preferentially to fail if the mantle is submitted to undue stress and, for this purpose, the internal threads are made less mechanically strong than the external threads so that failure preferentially takes place at the internal threads.  Thus, on failure of the connec-tion between the mantle and the shaft, damage to either of the latter is avoided.

Abstract: ABSTRACT:              A device for digitizing  an analog signal whose mean value is constant, comprising a delta modulator which is adapted to sample the signal during successive time intervals, each of which has a duration which corres-ponds to n pulses of a clock pulse generator, and to supply m (m < n) pulses per time interval, m being depen-dent on the difference between the values of the signal at the beginning g and at the and of the interval. The output of the delta modulator is connected to a correction   air-cuit which is constructed as a digital high-pass filter in order to remove error signals which are added to the  sig-nal due to inaccuracies of the delta modulator.

Abstract: ABSTRACT OF THE DISCLOSURE       A purge gas unit is provided for establishing an enclosed zone for purge gas within a tube or pipe having portions which are to be joined by welding at a predetermined location relative to the length of the tube or pipe.  The purge unit includes at least one cone to be positioned on one side of the location where the welding is performed and a second cone positioned on the other side of the location.  A purge gas supply tube is connected between the cones and has at least one opening therebetween through which purge gas is supplied to the weld zone in in the pipe or tube between the cones.  The gas supply tube extends through one of the cones beyond the weld zone defined between them and is connected to gas supply means.  The gas supply tube also aids in withdrawing the cones from the pipe or tube after the weld is completed or, with tubing which is moved continuously and butt-welded along a longi-tudinal seam, the gas supply tube can be used to hold the cones in a stationary position as the tubing is moved longitudinally during the forming and welding operations.  In a preferred form, the cones face in a common direction.  Also, the gas supply tube between the cones can be flexible to enable the cones to be withdrawn through a curved portion of the pipe or tube after the welding operation when the pipe or tube is stationary.

Abstract: ABSTRACT OF THE DISCLOSURE           Soluble sulfide residue, and small amounts of cyanide and oil, can be removed from scrubber water waste, particularly such waste produced by the process of manu-facturing polyolefins from natural gas condensate, by adding to the scrubber water waste a pickle acid waste, typically from steel operations, in an amount containing sufficient dissolved ionic iron to essentially completely react with all sulfide present and to precipitate it as iron sulfide.  The cyanide ion can react to form iron ferrocyanide, which is substantially coprecipitated with the iron sulfide.  Small amounts of oil present can also be coprecipitated.

Abstract: ABSTRACT           The disclosure relates to a hose clamp comprising a generally circular band having a plurality of longitudin-ally spaced laterally extending slots at one end and a clamp housing engaged with an opposite end of the clamp band.  A portion of the opposite end of the band within the housing is provided with a pair of upstanding continu-ous ears at the laterally spaced outer extremities thereof for engagement with the laterally outer edge portions of the one end of the band.  A screw is journaled in the housing and has a thread engageable with the slots.  A thin tough ductile plastic tape having a stretch coefficient of approxi-mately 70% is secured to the inner face of the band and covers the slots exposed to a hose being clamped by the clamp to minimize extrusion of the hose through the slots upon tightening of the clamp about the hose.  The tape also permits engagement of the screw thread within the slots without rupture of the tape.  The plastic tape is spaced inwardly from the edge portions of the one end of the band to provide a metal bearing surface thereon for direct metal to metal engagement with the ears on the opposite end por-tion of the band.
